Diagram illustrating the structural relationship between grabens and horsts Infrared-enhanced satellite image of a graben in the Afar Depression. In geology, a graben (/ ˈ ɡ r ɑː b ən /) is a depressed block of the crust of a planet or moon, bordered by parallel normal faults.

2018年1月8日 · The Grabens in The Needles district of Canyonlands is a system of linear collapsed valleys caused by the movement of underlying salt layers toward the Colorado River canyon. The grabens begin near the Confluence of the Green and Colorado rivers and run roughly parallel to Cataract Canyon for 25 km, veering slightly westward before they end.

Diagram of horsts and grabens. In geology, horst and graben (or range and valley) refers to topography consisting of alternating raised and lowered fault blocks known as horsts and grabens. The features are created by normal faulting and rifting caused by crustal extension. [1]

2020年4月22日 · This process, called extension, can stretch the crust up to 100% of its original size. As the crust is strained in this way, normal faults develop and blocks of the crust drop down to form grabens, or valleys. The end result of this is …

Horsts and grabens may range in size from blocks a few centimetres wide to tens of kilometres wide; the…

2015年10月12日 · Grabens and horsts indicate that the earth’s crust has been extended or pulled in opposite directions. The word graben comes from the German word for “ditch.” In 2012, grabens were found on the surface of the moon by NASA’s Lunar Reconnaissance Orbiter.

The meaning of GRABEN is a depressed segment of the crust of the earth or a celestial body (such as the moon) bounded on at least two sides by faults.

USGS Graben: A depressed segment of the Earth’s crust bounded on at least two sides by faults Long, narrow trough bounded by one or more parallel normal faults. Down-dropped fault blocks are caused by tensional crustal forces A block of land bounded by parallel faults in-which the block has been downthrown, producing a distinctive structural…

The origin of the majority of grabens is believed due to lateral tension, i.e., rift troughs with normal faulting. Common examples are those formed on domes or anticlines (crestal grabens). Similarly, grabens are associated with block faulting in areas of regional upwarp and stretching.
